Arc reactor print?

I hate to ask this but after about 30 minutes of searching I give up.

I remember someone had posted a printable paper disc of an arc reactor. The disc was meant to be placed in front of a light for a cheap quick arc reactor look. Ive got a LED light for my suit, but I cant find the damn disc print any more. Help a brother out?

I made a few a while ago. Not exactly accurate, but they get the job done. The outer rings should print to 80mm, which happens to be the exact outer dimensions of 3" PVC pipe.







I used a CNC mill to mill mine out of styrene and it worked well enough.

Here's a link to a paper print arc reactor bezel in use.
